Synthesis, Properties, and Humidity Resistance Enhancement of Biodegradable Cellulose-Containing Superabsorbent Polymer

Table 1

The absorption of SAP after modification by different surface cross-linking reagents.

Types of cross-linking agents	Water absorption rate (g/g)	Moisture absorption (humidity resistance)	Gel strength	Dispersion
Blank	903	Easy	Low and viscous	Poor
Ethylene glycol	861	Easy	High, viscous	Better
Diethylene glycol	859	Poor	High, relatively dry	Better
Epoxy chloropropane (ECH)	832	Poor	High, dry	Good
Ethylenediamine	878	Easy	High, viscous	Better
Polyethylene glycol	856	Easy	High, viscous	Poor
